Epoxides are ethers in which the oxygen atom is part of a ring of three atoms. The element is similarly found in almost all biomolecules that are important to (or generated by) life. Oxygen reacts spontaneously with many organic compounds at or below room temperature in a process called autoxidation . [127] See more Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with … See more Properties and molecular structure At standard temperature and pressure, oxygen is a colorless, odorless, and tasteless gas with the molecular formula O 2, referred to as … See more One hundred million tonnes of O 2 are extracted from air for industrial uses annually by two primary methods. The most common … See more Oxygen storage methods include high-pressure oxygen tanks, cryogenics and chemical compounds. For reasons of economy, oxygen is often transported in bulk as a liquid in specially insulated tankers, since one liter of liquefied oxygen is equivalent to 840 … See more Early experiments One of the first known experiments on the relationship between combustion and air was conducted by the 2nd century BCE Greek writer … See more Photosynthesis and respiration In nature, free oxygen is produced by the light-driven splitting of water during oxygenic photosynthesis. According to some estimates, green algae and cyanobacteria in marine environments provide about 70% … See more Medical Uptake of O 2 from the air is the essential purpose of respiration, so oxygen supplementation is used in medicine. Treatment not only … See more WebIt's not the cyclic ring you've described, but there do exist exotic allotropes of oxygen such as octaoxygen. The catch? They're only stable at hundreds of thousands of atmospheres …

WebThere are other functional groups that contain oxygen atoms. A carbonyl group is formed when an O atom and a C atom are joined by a double bond. In this diagram, the R group represents any hydrocarbon chain: If one bond of the carbonyl group is made to a hydrogen atom, then the molecule is further classified as an aldehyde.When naming aldehydes, the … WebWhen some molecular structure release a hydrogen ion (hydroxide), the water molecule, being electronegative (hoging electrons), take the hydroxide, thus forming Hydronium, with three Hydrogen molecules and one Oxygen molecule.
